Serbian Despotate

The Serbian Despotate (Serbian: Српска деспотовина) was a medieval Serbian state in the first half of the 15th century. Although the Battle of Kosovo in 1389 is generally considered the end of the medieval Serbia, the Despotate, a successor of the Serbian Empire and Moravian Serbia, survived for another 60 years, experiencing a cultural and political renaissance before it was conquered by the Ottomans in 1459. Before its conquest the Despotate nominally had a suzerain status to the Ottoman Empire, Byzantine Empire and Kingdom of Hungary.After being fully subjugated to the Ottoman Empire in 1459, it continued to exist in exile in the medieval Kingdom of Hungary until the mid-16th century. Pavle Bakić was the last Despot of Serbia to be recognized by both the Ottoman and the Habsburg Empires.

HISTORY
After Prince Lazar Hrebeljanović was killed in the Battle of Kosovo on June 28, 1389, his son Stefan Lazarević succeeded him. Being a minor, his mother Princess Milica ruled as his regent. A wise and diplomatic woman, she managed to balance the Ottoman threat as the Ottoman Empire was in a turmoil after the Battle of Kosovo and the killing of Sultan Murad I. She married her daughter, Olivera, to his successor, Sultan Bayezid I.

After the battle, in 1390 or 1391 depending on source, Serbia became a vassal Ottoman state, and Stefan Lazarević was obliged to participate in battles if ordered by the Ottoman sultan. He did so in the Battle of Rovine in May 1395 against the Wallachian prince Mircea I and the Battle of Nicopolis in 1396 against the Hungarian king Sigismund. After that, Sultan Bayezid awarded Stefan with the majority of the Vuk Branković's land on Kosovo, as Branković sided with the Hungarian king at Nicopolis.

When Timur's army entered the Ottoman realm, Stefan Lazarević participated in the Battle of Ankara in 1402, in which the Ottomans were defeated and their leader Bayezid was captured. Returning to Serbia, Stefan visited Constantinople where the Byzantine emperor Manuel II Palaiologos granted him the title of despot. In previous years, this title would mean that the despot would rule some vassal state; however, as the Byzantine Empire was too weak to assert such a rule and Serbia was not its vassal state, Stefan Lazarević took this title as the personal style of the Serbian monarchs.
